mathematics can help students to increase their interest in science and mathematical literacy 
gives. Below we will focus on the logical issue that can be used in grades 7-9 math classes.
The issue. Norphan,  Shaʹdrach, Meʹshach and A· bedʹne ·go took the first four places.
When asked who they were ranked, three people answered: Norphan is neither 1st nor 4th ; 
Gandhi-2nd place; Mahmoud is not 4th, they replied. What places did each of them occupy? 
Solution: As a result of the condition of the issue, we will create the following table 
O'rin 
Normurod 
Gandhi 
Mahmud 
Nurbek

If Norʹdrach, Meʹshach and A· bedʹne·go did not take 1st place or 4th place, and Shaʹdrach, 
Meʹshach and A·bedʹne·go finished 2nd, nor did Norphan take 3rd place. If 2nd and 3rd 
places were taken and Mahmoud did not finish 4th under the terms of the matter, then he
was ranked 1st. As a result, Nurbek took 4th place.

Answer: Mahmoud 1st, Shaʹdrach, Meʹshach and A·bedʹne·go 2nd, Normurod 3rd, Nurbek 
4th. 
In a nutshell, to develop students' logical thinking abilities in classrooms, they need to 
develop their intellectual qualities and general mental abilities. N.S.Leytes shows that 
some of the conditions of activity and self-regulation are hidden in the characteristics of high 
nervous activity, which are important for the composition of common mental abilities is one 
of the internal conditions. Given the abundance of logical issues even in the composition
of TIMSS and PISA programs, the world's international evaluation systems today solve 
logical issues and make it for readers teaching at an excellent level is relevant.
